SW Technical Review Workgroup

The Stormwater Technical Review Workgroup (TRW) is a group of stakeholders that met between January 2012 and January 2013 to resolve specific concerns with the state stormwater program. The TRW and the Division of Energy, Mineral and Land Resources agree that the resulting work products meet the intent and spirit of the state's stormwater rules and statutes.

These documents constitute guidance for the engineering and regulated community and should not be considered requirements by the division. The goal in developing these documents was to provide additional tools and flexibility to the engineering community in meeting stormwater rules and statutes. Such alternatives are available through stipulations in 15A NCAC 2H .1008(h), which allows alternative designs that "provide equal or better stormwater control, equal or better protection of waters of the state and result in no increased potential for nuisance conditions."

TRW work products include:

Memo Detailing Options and Clarifications Prepared by Stormwater TRW

Definitions of Frequently Used Stormwater Terms

Options for Meeting Diffuse Flow Provisions

Voluntary Options to Use the SCS Method

Options for Complying with the No Direct Discharge to SA Waters Requirement

Standards for Relaxing the Separation Between Infiltration Systems and the SHWT
